The format of data sent to SLC/PLC-5 PLCs:
For large received data packets:
• The data will automatically be placed in sequential files.
• The files must be 256 integers in size with the exception of the last file. The last file may be shorter than
256 integers as long as the total length of all files in the sequence is sufficient to hold the largest receive
packet, plus two integers for the sequence number and length parameters.
• All data will have been transferred to the PLC when the sequence number is updated.
